GEM28 - Econ

Introducing iOptron’s new compact next-generation German equatorial mounts the GEM28! Like their predecessors, the GEM28 is designed with portability in mind, weighing in at only 10 lbs it can support payloads up to 28 lbs -- an incredible 2.8 payload-to-self weight ratio. We achieved this using design methods developed to reduce mount mass in our GEM family of mounts. These German EQ versions were created to satisfy consumer that prefer a more traditional mount and to function at higher latitudes. Building on the legacy of earlier GEM models we have added features for convenience and functionality: a positive lock gear engagement system that's easy to use even when wearing gloves the built-in Wi-Fi enables unparallel connectivity, and recordable permanent periodic error correction (PPEC) to repeat optimal PEC training sessions. Regarding functionality the GEM28 delivers precise pointing and accurate tracking. The GEM28 sets the new standard for compact German equatorial goto mounts. The GEM28 is equipped with the latest advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. The 212,000+ object library ensures you’ll never run out of targets to see or image. The Go2Nova® Hand Controller is intuitive to use and its large 4-line LCD screen simplifies the process of setting telescopes and locating objects. The GEM28 ECON does NOT come with a supporting tripod or pier; it has an AccuAlignTM optical polar scope installed for quick and easy polar alignment.
